Every request to the MetaLink API requires an API key. You can pass it in two ways: 
curl "https://api.metalinkapi.com/v1/metadata?url=https://example.com" \
  -H "X-API-Key: ml_live_YOUR_KEY_HERE"

​
Query Parameter

curl "https://api.metalinkapi.com/v1/metadata?url=https://example.com&api_key=ml_live_YOUR_KEY_HERE"
The header method is recommended. Query parameters may be logged in server access logs and browser history.

​
Key Format

All MetaLink API keys use this format: 
ml_live_ + 32 hex characters
Example: ml_live_de5c435f025332da7a0d07a21baeb95f

​
Getting Your Key

  1. Sign in at the Dashboard
  2. Click Create API Key
  3. Copy the key immediately
API keys are shown only once at creation. They are stored as SHA-256 hashes — we cannot retrieve them for you. If you lose a key, deactivate it and create a new one.
